I am a senior researcher/engineer at Bytedance. Previously, I served as a senior researcher at Tencent (Recruitment Talents Program: "技术大咖 "). Before that, I earned my Master's degree from Department of Automation, Tsinghua University, supervised by Prof. Qionghai Dai and Prof. Lu Fang, and meanwhile, I worked closely with Prof. Yebin Liu and Lan Xu.

My work mission is to capture and understand dynamic human-centric scenes in the real world, and digitalize humans, objects, and events for immersive application in virtual and augmented reality. My research primarily centers around computer vision and graphics, especially human 3D generation, avatar creation, 4D reconstruction, neural rendering, motion capture, and related areas.

I am looking for full-time partners and research interns, please feel free to drop me an email if you are interested in the topics above.

    1. 3D Generation

     

          HumanSplat: Generalizable Single-Image Human Gaussian Splatting with Structure Priors
    Panwang Pan*, Zhuo Su* (Project Lead), Chenguo Lin*, Zhen Fan, Yongjie Zhang, Zeming Li, Tingting Shen, Yadong Mu, Yebin Liu (*Equal Contribution)
    Neural Information Processing Systems Annual Conference (NeurIPS), 2024.

    We propose HumanSplat, a method that predicts the 3D Gaussian Splatting properties of a human from a single input image in a generalizable way. It utilizes a 2D multi-view diffusion model and a latent reconstruction transformer with human structure priors to effectively integrate geometric priors and semantic features.
